Between 5 and 20 percent of the population are bound to get the flu each year, according to Inman. Of those who get it, one in 1,000 die. Those deaths aren't always directly attributable to the flu, especially when victims are older and could have other health conditions, Inman said.

Nancy Cook with the Visiting Nurses Association gives William Tinsley of Titusville a high dose flu shot at Senior Fest. Hundreds of seniors have packed the Melbourne Auditorium as part of the the 16th annual Senior Fest on Friday. The event featured a host of vendors representing both businesses and public agencies including the Titusville, Satellite Beach, West Melbourne, Melbourne Police Departments and the Brevard County Sheriff's Office.

Local health officials work with hospitals, clinics and doctors around the county to tally the number of flu cases in Brevard each year.

Like every year, Inman said, "the flu will come, and very likely we will have some deaths, so please get vaccinated."

Flu vs. cold

The flu and the common cold are both respiratory illnesses but they are caused by different viruses.

The flu is worse than the common cold, and symptoms are more common and intense.

Because colds and flu share many symptoms, it can be difficult to tell the difference between them based on symptoms alone. Special tests that usually must be done within the first few days of illness can tell if a person has the flu.

The symptoms of flu can include fever or feeling feverish/chills, cough, sore throat, runny or stuffy nose, muscle or body aches, headaches and fatigue (tiredness). Cold symptoms are usually milder than the symptoms of flu. People with colds are more likely to have a runny or stuffy nose. Colds generally do not result in serious health problems.
